As disclosed in the accompanyingdrawings M denotes "amast of predetermined dimensions and which has its lower endlrotatably engaged with the bearing 1. The upper end of the mast M'isprovided'with an upstanding trunnion 2 which is loosely directed through the central portion of the plate 3. Coacting with the plate 8 are the. guy lines whereby the mast M is effectively maintained in avertical position yet capable of rotation.

Extending outwardly from the mast and preferably at rightangles thereto is a boom 13 and which boom is immovable relative to the mast M. The outer end portion of the boom B and the upper end portion of the ing the locking meansforthe'swinging bot tom panels as comprised in the receptaclef mast M are connected by the brace member* 5 whereby an effective support is afforded for the outer end portion of the boom B.

' The outer end portion of the boom B is provided therethrough with the"ve1.'tically' disposed opening 6 in which is rotatably mounted the pulley 7 over whichis directed the flexible. member F. One end of the member F- is anchored to the bracket 8 dc-" pending from the boom B at a point inwardly of the opening and the opposite end portion of the member is adapted to be hitched to a draft team or a suitable pulling horizontally or winding mechanism. The member F after leaving the pulley 7 is disposed over a pulley 9 rotatably supported by the upper portion of the mast M and then under the pulley 10 engaged with the lower portion of the mast.

The member F intermediate the pulley 7 and the bracket Sis disposed under the pulley l1 rotatably supported within. the frame or body 12. In swivel connection with the lower end of the frame or body 12 is an eye member M and interlocking with the eye member 14 is a hanger H including the oppositely arranged and upwardly facing hook members 15. Engaged with the hook' members 15 are the central portions of the yokes 1 6 and the extremities of the yekes 16 are engaged with'the upstanding" ears or brackets 17 carried by the corner portions of the receptacle R. It will be self-evi-i dent that when strain is imposed upon the member]? the .receptacleR will-be elevated or.hoisted,an.d vice versa. I

straddling the outer end portion of the boom B and suitably spaced longitudinally thereof are the supporting members S in the form of an inverted U with the intermediate portions thereof resting upon the top of the boomand secured thereto by the bolts 18- or-equiva-lent fastening means. The side arms 19 0f the members S depend below the boom B and terminate in the bearings 20 in which are fixedly secured the rods '21 arranged in parallelism: and extending I01]: gitudinally of the boom B.

Pivotallyengaged at their lower portions with the rods 21 arethe transversely alined upstanding locking members or plates 22 and the upperen'd portions of said members or plates 22 are constantly urged inwardly through the medium of the expansible membore 23 interposedbetween the upper portions of. said. members or plates and the disposed and outstanding brackets 24 secured at their. extremities to the depending arms 19 of the members S;

The bolts or the like which secure the brackets 24: to the depending arms 19 each coa-ets with a. pair of transversely alined arms 19 and'al'l'ords means for connection with the burs or stops 2G engaged thereon, and contacting with the inner faces of the arms 19 to maintain the arms. 19 or more particularly the depending portion thereof againstrelative movement. Extending outwardly from. the upper end of the; member 7 or frame 12 is the elongated shank 21 tor:--

minating in the enlargement or head 28 The-outer or upper face o-f'the head 28- 1s conical in form as indicated at 29 that asthe frame or member 12 is elevated. or

hoisted through the medium of the flexible member F the head or enlargement28 will readily pass between the locking members or plates so that the upper edges ofsaid members or plates may engage beneath the head or enlargement 28 for maintaining the frame or member 12 and the elements carried thereby in an elevated or hoisted position.

Secured to the under face of the boom B directly above the plates is a housing or boxing 30 having itslower face open and of a width slightly-in excess of the radical di-' ameter of the enlargement orhead 28. The housing or boxing 30 receives the head or enlargement 2S and serves to protect the boom Bagainst injury by contact of said head or enlargement: therewith and also serves to facilitate the locking engagement of themembersor plates 22' with theenlargement or head 28 as said'head or enlarge merit 28 is neld by the housing or boxing 30 againstundue lateral movement when the members or plates 22 are in operative en gagement therewith.

Secured to the outer face of eaclr of the members or plates is an outstanding arm 31 terminating in an upwardly directed extension 32' and which extension is normally substantially vertically disposed. Rotatably supported by each pair of horizontally alined arms 19 of the members S is a shaft 33 provided with anupstatnding crank 3st adapted to contact upon outward swing" ing movement withthe upper end portion of an adjacent extension 321 of an arm 31. The forward end portion of one of the arms is provided with the depending extension 35 with which is operatirely engaged a rigid link 36 also operativelyconnected with an inwardly and upwardly directed extension 37 arranged at the outer end portion ofthe second shaft 33. By this arrangement both of the shafts 33 will be causedto rotate in unison but in reverse clirectionlso. that such unitary movement will: result in freeing the members or plates 22 from the head or en largement 28 of the shank 27 when it is desired to lower the frame or member l2'and the elements supported thereby- V In order to: impart the necessary out ard rocking movement to the cranks one of the shafts 3-5 is provided? with the in wardly directed extension 38 which has its outer? end, portion rotatably supported by the bearing engaged with the mast M. The extension 38 is provided with the upstanding: arm lO through the outer or free end of which is'securetl a flexible member F. The member F is of a length to be readily grasped by an operator so that w it is desired to release the frame or member 12, it is only necessary to pull? upon the member F. Interpomd' between the arnr tO and, the mast M' is a. retractile member 41 ,llf.

which serves to return automatically the cranks 3s=inwardly 'when' the memberl is is member F.

l The receptacle It may be constructed in any desired manner and be of any preferred capacity but as herein disclosed the bottom of the receptacle comprises't'wo swinging sections 43 hingedly connected at their outer longitudinal margins With'the rod i l supported by the depending bearings 145 carried by the sides of the receptacle B. When the sections 43 are" at the limit" of their swinging movement tow aid the V recep} ta'cle' R- the bottom. of such receptacle is substantially closed. "1

The Opposite ends of eachof thesections l3 adjacent the free longitudinal margin thereof is provided with the outwardly directed extensions 46 and coa'cted' with each of said extensions 4:6 is a holdingd'og or latch 41 pivot/ally engaged with the end wall of the receptacle R. Each-end of the receptacle It is provided with-' a pair of holding dogs or latches 4:7 and 'rotatably supported by the end of the receptacle R and between said-' latches or dogs 47 below 7 their pivots 48 is'a cam member 4:9. Upon rotation of the cam member ll) in one direction it will be at once'understood that the latches or dogs 4L7 will becau's'ed to-move in unison but in reverse directions so that the latches or dogs will be disengaged from the extensions 46 so that the sections 43 may drop so that the load carried by the receptacle B may be readily dumped or discharged therefrom. v V

7 Each of the cams 4:9 is provided with an upstanding lever 50. Operatively engaged with the upper end portion of each of the levers 50 is a pitman 51 which is also operatively engaged with a rock arm 52 carried by an end portion of the shaft 53 supported by a side of the receptacle R- and extending in a direction longitudinally of each of the bottom sections 43,

The rock arm 52 are reversely directed as particularly illustrated in Fig. 1 and one of the levers 50 is extended and affords an operating handle 54; and this lever is disupon the receptacle R is lowered.

and the cams in a position whereby no obstruction is offered to the engagement ofthe latches or dogs 47 with the extensions 46.

Each'pair of latches or holding dogs 47 above'their pivots 48 areconnected by an expansible member 57 which serves'to constantly urge the lower or working ends of the latches or'dogs 4-7 inwardly so that the desired engagement of the latches or dogs 47 with the extensions 46 is assured.

My present invention is particularly adapted for use in the removing or ensilage from a'pit silo and in practice the mast is initially swung or rotatedlto position the boom above the silo so that the receptacle R can be lowered therein. After the receptacle Rhas been loaded, strain or pull is imposed upon the member F through the mediuln of a draft animal or other means and which results in the elevation of the rece'pta-cle R until the member or frame F or more particularly the shank 27 thereof 'jis engaged with the members 01 plates '22. The mast M is then swung to position the boom-B above the vehicle whereupon pull is imposed upon the arm 40 to release the members' orplates 22 from the shank 27 where- After the receptacle R has been properly positioned desired pull is imposed upon the handle 54 which results in the release of the sections 43 whereuponthe contents of the receptacle R will be readily dumped or discharged into the receptacle. 7 x a From I the foregoing '-description, it is thought to be obvious that a loading apparatus constructed in accordance with my invention is particularly well adapted 'for use by reason of the convenience and facilinvention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
